The default allocation policy for LVM ("normal") is to use an
arbitrary PV that has space. So this means that unless you say so,
you w

Both (MD) RAID-1 and RAID-10 will work this out by themselves, by
the way, and tend to read from the fastest device.

Neither LVM nor MD will have a problem with member devices changing

If you use mdadm for RAID you can mark the slower disk as 'write-mostly'
to get more read speed.

Of course, but can it make any data damage to lvm?

Hi Kamil,
I don't know, if this is working at all. The reason for this, is, the BIOS
might cause trouble, because it might not always detect the drives in the
correct order.
For example, in my case I have several SATA drives, conn

Speed differences will occur because reading and writing from/to the
SSD will be much faster.

Debian box with LVM
LVM uses 2 PV - raid devices each uses 2 HDD (rotating)
discs (with sata interfaces).
Now I am considering replacing one PV with md device constisting of SSD
discs, so LVM will be have one "HDD" based pv and one SSD based PV.
